Success Story: Integrated communication
for a modern motorway infrastructure

As part of the project, Commend Slovakia implemented a comprehensive voice communication solution—an emergency communication system for the highway, an intercom system for the highway operator’s facility, as well as an IP telephony system for business communication. Commend, in collaboration with its partner—Photon Meissener Technologies—developed a completely new design for the highway emergency columns, with both it design and internal equipment meeting the requirement of technical regulations in the Czech Republic.

 The highway emergency columns are equipped with the ET908H IP communication module and an additional EB8E4A I/O module, through which the status of cable shaft covers located along the highway, door contact statuses, and the power supply status are transmitted to the SCADA system. The emergency columns features remotely controlled lighting via a dusk sensor. Calls from the emergency columns are routed to the CD800 operator workstation or to the relevant regional emergency operations center. The emergency call system is interconnected with the DMR radio communication system and allows the operator to communicate directly from their workstation with the desired group of radio stations. WS300VCM series intercom stations are installed within the facility, either built into Commend CSTHREE entry/exit posts or mounted on the wall at the facility entrances. The camera modules of the intercom stations are integrated into the site’s security camera system with Genetec VMS. The entire system is integrated into the SCADA system on the WINCC platform via the OPC UA interface. 

All software components of the solution—the VirtuoSIS communication server, the Commend STUDIO application server, the Commend OPCServer for integration into the SCADA system, and the Mitel IP PBX server—are installed on a virtualized Hyper-V server platform with highavailability functionality.
